PIPE-JACK.

Specification of Letters Patent.

Patented June 3, 1919.

Application filed January 30, 1919. Serial N 0. 274,119.

To all whomit may concern:

. Be it known that 1, JAMES H. JONES, a citizen of the United States,residing at Etowah, in the county of McMinn and State of Tennessee, haveinvented certain new and useful Improvements in Pipeof which thefollowing is a specification. 7

The present invention comprehends generally improvments in that class ofinventions known as pushing and pulling and more particularly relates toan improved pipe jack.

It is the principal object of this invention to provide a device of theabove mentioned character designed to be used for separating pumpinjector and boiler check connections and for other pipe work, thecomponent parts being of novel construction and arranged so as to beeasily adjusted relative to each other.

More particularly this invention consists in the provision of a deviceof the above mentioned character embodying an attaching and supportingclamping bracket for effectively supporting the operating parts, thebracket being of novel construction and is capable of being quicklyapplied and detached.

It is a more specific object of this invention to provide a device ofthe above mentioned character wherein the coacting adjusting members areof improved construction and are mounted in the attaching and supportingbracket in a manner so that they can be conveniently adjusted foraccomplishing the desired purpose.

Among the other aims and objects of this invention may be recited theprovision of a device of the above mentioned character wherein thenumber of parts are few, the construction simple, the cost of productionlow and the eiiiciency high.

Other objects, as well as the nature, characteristic features and? scopeof this invention will be more readily apparent from the followingdescription taken in connection with the accompanying drawings 7 andpointed out in the claims, forming a part of this specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is aside elevation showingthe device applied in anoperative. position,

Fig. 2 is an enlarged fragmentary longitudinal sectional detail,

Fig. 3 is a cross sectional view taken through the device showingparticularly the attaching and supporting bracket.

Fig. 4.- is an enlarged sectional detail showing the means forconnecting the clamping brackets together, and

Fig. 5 is a detail in plan of the head of the jack.

Similar characters of reference are employed in all of the abovedescribed views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings, there isprovided the improved attaching and supporting clamping bracketsgenerally indicated by the numeral 1, which in the present instancepreferably consist of coacting sections 2- and 8,. The section 2 isformed of metal and has a portion bent arcuate or semi-circular to forma clamping jaw while a straight portion 4 continues therefrom andterminates in a tubular supporting portion 5 for a purpose which willappear. The straight portion 4 is formed with a transverse opening orslot while projecting from the straight portion at the ends of the slotare cars 6 also for a purpose to appear. Another relatively straightportion 7 continues from the outer end of the jaw and is formed with anopening. The other section 3 of the bracket is bent to provide asemi-circular jaw contacting with the jaw on the section 2and is formedat its inner terminal with an offset hinged ear 8 which'is designed tobe passed through the opening or slot in the straight portion i and 1arranged in alinement with the ears 6 while passed through the aliningears 6 is a bolt 9 which serves as a means for pivotally connecting thesections 2 and 3 together, the bolt being retained in positiondesirablythrough the instrumentality of a nut 10. The jaw of the section3 terminates in a relatively straight portion 11 and is designed to bedisposed opposite to and in spaced parallel relation with the straightportion 7 of the section 2 subsequent to the passing of the jaws about apipe section 12 or other piece of work, beingfinally engaged by a screwor other retainer 13 which acts to clamp the jaws in frictionalengagement with the section or pipe 12.

With a view toward providing the improved'coacting adjusting members,there is employed a sleeve member 14 which is rotatably receivable inthe tubular receiving and supporting body 5, the inner surface beingprovided with screw threads 15 for a pur pose which will presentlyappear while this sleeve member is formed at one end with a head 16 theouter surface of which is desirably octagonal as at 17 and each flatface is formed with an inwardly extending socket 18 adapted to receivean adjusting wrench (not shown) for a purpose whichwill presentlyappear. Adjustably mounted within the sleeve member 1 1 is acorrespondingly eXteriorly threaded screw member 19, one end of which isformed with a head 20 the fiat faces of which are provided with wrenchengaging sockets 21 to facilitate the adjustment of the screw member. Inaddition the outer edge of the head 20 is roughened as at 22 tofacilitate the anchoring of the screw member against the casing fromwhich the pipe section 12 is being removed. The opposite end of thescrew member is formed with an inwardly extending circular socket 24designed to receive the stem 25 of the pointed swivel head 26. A portionof the head is formed with a plurality of flat faces 27 each of which isin turn formed with an inwardly extending wrench engaging socket 28.

In use, assuming that the clampingjaws of the sections 2 and 3 areapplied about the pipe section 12 and that the head 20 of the screwmember 19 is arranged against the casing 23 with the screw member inturn engaged in the sleeve member in the receiving body as shown in Fig.1, to cause a separation of the section 12 from the casing 23 subsequentto loosening the connecting member. A suitable wrench (not shown) isemployed and is engaged with the socket 18 in the head 17 to rotate thesleeve member in the receiving body 5, this causing the sleeve member towork outwardly on the screw from the head 20 and inasmuch as the head 17abuts the body 5 and the clamp 1 is engaged on the section 12, thelatter will be moved away from the casing, the knurled or roughened face22 of the head 20 of the screw member preventing a. rotation of themember 19 during this operation. WVhen the parts are arranged as in Fig.2 the pointed swiveled head 26 is engaged for instance against a casingor other piece of work (not shown) while the clamp as usual is appliedabout a pipe section 12 and when the parts are arranged in this positiona wrench (not shown) is adapted to be engaged with the socketed head 20to rotate the screw .member 19 while another wrench (not shown) may beengaged in the socket 18 to prevent the rotation of the sleeve me. her16 and cause the latter to move outwardly or away from the swivel headduring the rotation of the screw member, this action also causing aseparation of the pipe section 12 from the casing (not shown).

Although there has been particularly described the tworuses andoperations of the invention, it is desired to be understood that thepresent combination and arrangement is not limited to these specificuses but may be used by plumbers, mechanics, et cetera, for pipe workand work of other characters.

It is believed in view of the foregoing description that a further ofthe operation of the invention is entirely unnecessary. Likewise, it isbelieved that the advantages of the invention will be readily apparent.

Still further embodiments than those herein especially defined may beresorted to as conditions or preference in ay dictate, as may be inkeeping with the hereto appended claims.

Having thus fully described the invention, what is claimed as new anddesired to be secured by Letters Patent, is V 1. A pipe j ackof thecharacter described including a sectional attaching and supportingclamping bracket, a tubular receiving body formed thereon, an interiorlythreaded sleeve member arranged inthe tubular body, a head on one end ofsaid sleeve member and designed for abutting engagement with one end ofthe body and also provided with a pluralityof sockets, a screw memberoperatively arranged in said sleeve member, one end of the screw memberbeing provided with a socket, a pointed head having a stem swiveled insaid socket, and another head integral with the opposite end of thescrew member and provided with a plurality of sockets.

2. A pipe jack of the character described including an attaching andsupporting bracket composed of a pair of metallic sections, othersections being bent to form an arcuate jaw, a straight portioncontinuing from one end of the jaw and having an opening therein, atubular receiving body continuing from the straight portion, earsprojecting from the straight portion at the ends of the opening, anotherstraight portion continuing from the opposite end of the j aw, the othersection being bent to form an arcuate j aw, an ofiset hinged ear formedat one end of the last mentioned jaw, pivotal means engaging the earsfor pivoting the sections together, astraight portion formed at theouter terminal of the last mentioned jaw, means detachably engaging thestraight portions with the outer terminals of the jaws for releasablyholding the jaws inclamping relation, and coacting adjusting members oneof which is operably mounted in the tubular body.

In testimony whereof, I affix my signature hereto. 7
